i

Device for packaging a flexible container, imitating a barrel, and corresponding manufacturing method

1. Field of the invention

The field of the invention is that of the manufacture of packaging, and in particular of decorative and / or ergonomic overpacks, in particular for flexible containers intended in particular to contain a liquid, viscous or pulverulent material, and for example a liquid such as wine or fruit juice.

2. Prior art

Liquid, viscous or powdery materials must be packed in airtight containers. For a long time, rigid containers have mainly been used, in particular bottles or similar containers.

More recently, flexible containers, bottles or pouches have been proposed for packaging a liquid, such as wine. This pocket, which can be self-supporting thanks to a suitable base, and has a tap for extracting the liquid. This type of container is known in particular under the registered trademarks "Bag in Box" or "BIB".

The flexible container is, as the case may be, sold without overwrapping, or in a parallelepipedic box, in particular made of cardboard, to form a "box-addition". This type of product is also known under the trademarks “Bag in Box” or “BIB”.

This solution makes it possible to condition a variable volume of liquid, for example from 25 cl to several liters of wine or fruit juice, and proves to be effective as regards the conservation of the liquid.

However, the pockets without overwrapping as much as the versions with cardboard packaging are unattractive, for example for installation on a table or buffet, and convey an image that is not very rewarding for the content.

There is therefore a need for a new presentation for this kind of container which has a new aesthetic, more stable and inexpensive.

3. Summary of the invention

The invention thus relates to a device for packaging a flexible container containing a liquid or viscous or pulverulent material, said container having an outlet conduit for the extraction of said material.

According to the invention, said packaging device is formed of two frustoconical baskets assembled, a lower basket and an upper basket, produced by means of an assembly of staves maintained by at least one circle, and each having a bottom and an edge of an open upper surface, said bottom and said edge being connected by a peripheral wall. Said baskets are assembled and secured to one another by the edges of their respective upper surfaces, after the container has been placed in one of the baskets, so as to have a general barrel shape. Said lower basket has a corresponding opening or pre-cutting, allowing the passage of said outlet duct.

Such baskets are known. However, their assembly according to the invention is new and not obvious. Indeed, they are intended to be used independently of each other, and to rest on their bottom. Here, the upper basket is turned over (the bottom is above and the opening (also called the upper part for abuse of language, in this turned-up position) is below.

And the edges of these two baskets are joined, for example using a central circle.

We thus propose a new type of overpack, well suited to flexible containers, simple and inexpensive to manufacture and assemble, and offering an original and interesting aesthetic appearance, imitating a barrel or a similar product, while retaining the advantages of the flexible container. (conservation, presence of tap, accessible via opening or pre-cutting ...).

Preferably, to optimize this barrel appearance, the two baskets are of identical or almost identical shapes and dimensions. However, in certain variants, different forms can be envisaged.

According to a particular embodiment of the invention, the joining of said two baskets and of said central circle is carried out by gluing.

Other assembly methods, definitive, for example by sewing, or temporary, for example by clipping, can also be envisaged.

According to a particular embodiment of the invention, one of said staves of said lower basket carries a pre-cut forming said opening.

In this case, said pre-cut stave can in particular be made of paper, cardboard or wood.

According to a particular embodiment of the invention, at least some of said staves, said at least one circle and said central circle are made of wood.

The invention also relates to a method of manufacturing such packaging, comprising in particular the following steps:

obtaining two baskets, a lower basket and an upper frustoconical basket, produced using an assembly of staves maintained by at least one circle, and each having a bottom and an edge of an open upper surface, said bottom and said edge being connected by a peripheral wall;

pre-cutting or cutting of an opening in one of the staves of said lower basket (before or after assembly of the basket);

placing said flexible container in said lower basket;

placing said upper basket on said lower basket, said upper surfaces being placed one on top of the other;

securing said baskets by the edges of their respective upper surfaces.

According to a particular embodiment of the invention, said step of joining said baskets comprises a step of bonding a central circle joining the two baskets.

4. List of figures

Other characteristics and advantages of the invention will emerge on reading the detailed description which follows, with reference to the appended figures, among which:

Figure 1 is a perspective view illustrating the two baskets constituting the packaging device of the invention; 2 shows the packaging device of the invention after assembling the two baskets of Figure 1;

FIG. 3 represents the packaging device of the invention after the two baskets of FIG. 1 are joined together;

FIG. 4 illustrates a variant basket, with a hexagonal section.

5. Detailed description of the invention

Figure 3 illustrates the packaging device 1 of the assembled invention, in which is stored a flexible container 2 intended to contain a liquid, viscous or powdery material.

In this example, the material contained in the flexible container 2 is a liquid, and more particularly wine or fruit juice. Of course, other liquids, food or not, can also be contained in such a flexible container, as well as viscous products (soap for example) or powder (flour for example). The invention can be applied in particular to wine, because the device has the general appearance of a barrel.

As illustrated in FIG. 1, the packaging device 1 consists of two baskets of generally frustoconical shape, a lower basket 3 and an upper basket 4. The lower baskets 3 and upper 4 are, in this example, substantially identical.

Only the lower basket 3 is described below. It is obviously understood that the upper basket 4 has a similar structure and that it is manufactured in the same way.

Thus, the lower basket 3 consists of a plurality of staves, or strips, 31 assembled, and held by an upper circle 32 and a lower circle 33. In this example, the staves 31 and the circles 32, 33 are made of wood.

The baskets are for example made of poplar wood unrolled: the logs are first unrolled and cut into thin strips (for example 0.8 to 1.5 mm) which will become the constituent elements of the overpack, staves and circles.

Optionally the wood can be stained or colored, in particular by means of food stain.

These elements can first be pre-dried, to reach a humidity level compatible for the application of a hot glue.

To obtain a basket 3, the staves 31 are arranged in a star (manually or by means of an automatic distributor) before being stamped between a die and a punch in order to give the staves 31 the shape of a basket. After stamping, the upper 32 and lower 33 circles are glued and brought into contact with the staves 31. The circles 32, 33 and the staves 31 are kept in contact until the adhesive has taken hold in order to hold the basket 3.

After assembling the staves 31 and the circles 32, 33, the lower basket 3 therefore has a bottom 35 (not visible) and an upper edge 36 which defines the open upper surface, or opening, of the basket 3. The bottom 35 and the edge upper 36 are connected by a peripheral wall 37.

Similarly, the basket 4 consists of staves 41, an upper circle 42 and a lower circle 43 which are held together according to the same method. The upper basket 4 therefore also has a bottom 45, an edge 46 and a peripheral wall 47.

Furthermore, the lower basket 3 has an opening 34, which allows the passage of an outlet conduit (not illustrated), conventionally equipped with a tap, arranged on the container 2 so as to allow the extraction of the liquid from the container. flexible.

The opening 34 is formed in one of the staves 31 forming the lower basket 3. More specifically, the opening 34 may be in the form of a precut 341 which weakens the stave 31 and which can be broken by the user of so as to pass the outlet conduit of the container 2 through the opening 34.

In a variant, the opening 34 is formed by a cutout of the stave 31 and it therefore suffices simply for the user to pass the outlet conduit of the container 2 through this opening 34.

In this example, the opening 34 is formed in the peripheral wall 37 of the lower basket 3. In a variant (or in addition), the opening 34 can be formed in the bottom 35 of the lower basket 3.

The opening 34 formed in one of the staves 31 of the lower basket 3 can be made prior to the provision of staves 31 in a star before stamping.

Before securing the upper basket 4 and the lower basket 3 with its opening 34, it is necessary to place the flexible container 2 inside the lower basket 3, as illustrated in FIG. 1.

The lower 3 and upper 4 baskets are then assembled and secured to form the packaging device 1 of the invention. To do this, the upper basket 4 is placed on the lower basket 3, as illustrated in FIG. 2. In other words, the edge 46 of the upper basket 4 is brought into contact on the edge 36 of the lower basket 3 .

As illustrated in FIG. 3, a central circle 5 is placed and fixed, for example by gluing, on the upper circles 32, 42 of the lower 3 and upper 4 baskets respectively, so as to join the two baskets 3, 4 to each other and get the packing device 1.

To do this, the central circle 5 is glued and then brought into contact with the two upper circles 32, 42 of the respective baskets 3, 4. The central circle 5 and the upper circles 32, 42 are kept in contact until the adhesive has taken hold.

The packaging device 1 of the invention therefore makes it possible to receive, in an aesthetic and original manner, by adopting the appearance of a barrel, a flexible container 2 containing, for example, wine. The packaging device 1 is simple to implement and has a low manufacturing cost.

Such a structure also makes it possible to ensure excellent stability of the packaging device 1 when it is placed on a table or sideboard.

In addition, the packaging device 1 protects the flexible container 2 during transport and handling in order to prevent the latter from being perforated.

6. Other aspects and variants

The general shape of these baskets in FIGS. 1 to 3 is essentially a truncated cone of revolution, the diameter of the bottom 35 being less than the diameter of the opening defined by the edge 36. Substantially different shapes can be envisaged for the trunk of cone, the guiding curve can substantially form a hexagon, as illustrated in Figure 4, or a polygon with more than 6 sides (it is desirable that the number of sides is at least 6, so that the central circle 5 follows effectively and without break the upper edges of baskets 3 and 4). An oval guide curve can also be considered.

In the example described above, the packaging device of the invention is intended for the transport and protection of a flexible container in the form of a flexible bag containing wine.

However, the packaging device 1 of the invention can also be used for transporting and protecting a flexible container 2 which may contain other materials / products, such as for example: milk, fruit juice, maple syrup, oil, vinegar, honey, detergent, liquid soap, etc.

The packaging device 1 can also be provided for flexible containers 2 containing foodstuffs such as flour, sugar, salt, pasta, etc.

The volume of the flexible container can be variable, from a few tens of centilitres to a few tens of liters, depending on the materials contained and the applications, the assembled baskets can, depending on the case, be similar to a keg, a barrel, a barrel, a barrel. , a barrel...

In a particular embodiment, an essentially cylindrical intermediate portion can be placed between the two baskets. In this case, two securing circles can be provided, a first securing the edge defining the opening of the lower basket to the lower edge of the intermediate portion and a second connecting the upper edge of the intermediate portion to the edge defining the opening of the basket superior.

Many variants of materials can be envisaged for the manufacture of circles and staves. Indeed, the device of the invention can be made of a material, or a combination of materials from wood, cardboard, paper, composite or plastic, in particular.

In the embodiment described, the stave 31 of the lower basket 3 carrying the opening 34 is for example made of cardboard or paper, in order to facilitate the implementation of the cutting or precut 341, and the other staves are in wood. It is also possible that the stave 31 is also made of wood.

The joining of the upper and lower circles with the staves is in this example carried out by gluing. It is possible, in a variant, to realize this joining by other means, by means of staples for example.

In addition, the central circle 5 is secured to the upper circles 32, 42 of the two respective baskets 3, 4 here also by bonding. It can be envisaged to achieve this joining by the use of retaining clips, staples or stitching. Certain types of attachment can in particular allow the reuse of the device.

In the example illustrated in FIG. 2, the edges 36, 46 of the baskets 3, 4 are simply brought face to face in order to allow the joining by means of the central circle 5.

In order to further facilitate the step of assembling the lower 3 and upper 4 baskets, complementary shapes can be provided on the edges 36, 46 of each of the baskets in order to allow the upper basket 4 to be interlocked with the lower basket

3.

In a variant of the invention, each of the baskets 3, 4 may have only an upper circle 32, 42. However, although the implementation of a lower circle 33, 43 is not compulsory, it is preferable in order to improve the robustness of the packaging device 1, and to maintain the general resemblance to a barrel.

The packaging device 1 can be delivered fully assembled with the flexible container 2 previously placed inside. The packaging device 1 can also be delivered disassembled, that is to say that the two baskets 3, 4 are not secured, so that the user, for example the supplier of the flexible container 2, can set up itself the flexible container 2 in the lower basket 3 and that it then secures the lower 3 and upper 4 baskets therebetween.

The packaging device 1 of the invention can be removable and reusable so that a user can exchange the flexible container 2, when the latter is empty, with another flexible container 2 full. If the flexible container 2 allows it, it can refill it and close the packaging device 1 in order to increase the number of uses of the packaging device 1.

Furthermore, the materials used to manufacture the packaging device 1, in particular wood and cardboard, can make it possible to recycle the packaging device 1 at the end of its life. The packaging device 1 of the invention is thus environmentally friendly.

The baskets 3, 4 and the central circle 5 constituting the packaging device 1 can be colored by means of a food dye, for example. They can, in addition, present a marking including, for example: a mark, data concerning the packaged product, advice on use, legal data, etc.

Furthermore, the lower basket 3 may have feet or an additional support (not shown) in order to further improve the stability of the packaging device 1.
